Abstract
A display device and a terminal are provided. The display device includes first pixel units and second pixel units arranged alternately along a first direction. In an energy saving mode, a control module is used for controlling one of the first pixel units and the second pixel units to emit light in a current display frame, for controlling another one to detect a threshold voltage of driving units of pixel driving circuits, and for controlling pixel units emitting light and pixel units for detecting to swap with each other. Energy consumption can be lowered, and detection time is sufficient.
